If the battery was completly dead and the alternator didn't work, a spark ignition engine would not start no matter how far it was pushed.

I know that. Push starting will turn the engine, hence the alternator. Obviously if the alternator is dead, you will not generate any electricity to spark the engine, but it works if you have a dead battery ( provided it's not internally damaged.) Older cars without computers would run without a battery, but newer ones need a certain battery voltage to operate.
